Bobble has an activated carbon filter which has a slight electro-positive charge, making it attractive to chemicals and impurities. As the water passes over the positive charged carbon surface, the negative ions of the contaminants are drawn to the surface of the carbon granules.

Bobble's carbon-based filter meets or exceeds NSF International Standard 42 chlorine, taste and odor reduction.

For best results, we recommend changing the filter after 2 months or 40 gallons/ 150L. Filter for use with Bobble only.
